Title: Procedure for advancing roadway support by lagging mats - ends of mats longitudinal wires are bent and attached by springs to support profile
Inventor: QUANTE HEINRICH
IPC: E21D11/15
Filed: 1974-12-17
Abstract: Procedure for advancing roadway support mines or tunnel driving by means of wire lagging mats by which the ends of some of the lagging mats longitudinal wires are U-shaped bent in a plane parallel with main axis of the support profile positioned at right angle to the longitudinal axis of the roadway. When the lagging mats are placed behind the supports the bent wire ends are positioned on the outside of the support and are inserted in a spring which is attached to a flange of the support on which the lagging mat is positioned. The spring consists of a spring steel plate (18) with an opening of a similar profile as the U-shaped ends of the wires. The opening which is smaller than the U-shaped wire ends is deformed by the inserted U-shaped ends and is further deforming by its attachment to the support profile.

Title: Catalytic reactor for making hydrogen - has compact construction with tubes located by spikes in base plate
Inventor: BAUMGAERTNER HEINRICH DIPL ING
IPC: F28D7/16
Filed: 1975-04-11
Abstract: Tubular cracking furnace for making H2 uses heat recovered from a high temp. reactor by means either of a cooling gas from the reactor or a condensing vapour from a boiler. The lower ends of the cracking tubes have spikes which locate in holes in a plate mounted at the base of the furnace and which can move axially in these. The plate contains a number of other holes which serve to let the gas enter the shell and is fixed to this shell, although there is a clearance when the unit is cold to allow for thermal expansion. However when the unit is at operating temp. this clearance disappears. The dia. of the cracking tube spike corresponds to the wall thickness of the cracking tube. Bushes can be located in the holes, not welded to the plate but held in posn. by rings welded to the plate. For use with high temp. gas reactors and can be used to make H2 for the hydrogenating coal gasification process. The structure is compact and can be included inside a single reinforced concrete structure with a nuclear reactor. To achieve a compact structure it is necessary to have very narrow clearances and transport or other movement can displace these in tubes simply suspended from above. In the system described, the thermal expansion of the cracking tubes is confined to axial movement by the spikes.
